SPECIFICATION forming part of Letters Patent No. 568,580, datedSeptember 29, 1896.

Application tiled July 24, 1896.

T0 all whom, it 1v1/ay concern.'

Be it known that I, WILLIAM RICHARD, a citizen of the United States, anda resident: of Bloomville, in the county of Seneca and State of Ohio,have invented certain new and useful Improvements in Shears; and I dohereby declare that the following is a full, clear, and exactdescription ot' the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to shears, scissors, and other similar instrumentsand its obj ect is to provide an improved construction of the same,whereby the tension of the handles may be readily regulated and thecutting edges so held with respect to each other as to produce the bestresults; to provide an improved lubricating device by which frequentoilin g is rendered unnecessary and the lubricating material evenlydistributed only at the points required; to provide improved means forconnecting the handles together, and to otherwise improve theconstruction, whereby I secure important advantages with respect toefficiency in use.

The invention consists, essentially,in a pair of shears or otheranalogous instruments comprising two handles with jaws and cutting edgeshaving a circular recess in the inner sides, a combined oil-cup and awasher lo cated therein, a yoke or compress for connecting the handlestogether, one side of which is seated in a groove in the outer side ofone of the handles and the other side provided with a screw-threadedboss with which engages a regulating headless screw, the inner end ot'which Vbears against one of the handles, as hereinafter fully describedand claimed.

It also consists in forming one or both of the jaws with shoulders orprojections at their outer edges, against which the inner edges ofremovable cutting-blades abut.

In the accompanying drawings, Figure l represents a side elevation of apair of shears or scissors constructed in accordance with my invention.Fig. 2 is a similar view showing the two `handles disconnected, lookingfrom the inner sides. Fig. 3 is a perspective view of the yokeorcompress. Fig. 4 is a similar Serial No. 600,386. (No model.)

side and showing the inclined groove therein.

In the said drawings the reference-numerals l and 2 designate thehandles of the shears, each provided with the usual finger-loops 3 andjaws 3, formed with cutting edges 4. Each of these handles is formed onthe inner side with circular recesses 5, which register with each otherwhen the handles are connected together, and Y in these recesses isseated a circular washer 6, having a central aperture 7 for containinglubricating material. This washer is preferably made of brass or copperand is formed with a peripheral groove tl.

The handle 2 on its outer side is formed with an inclined groove 9, inwhich is seated one of the sides of arectangular yoke or compress 10,which embraces the two handles, but which is suflciently large to permitof the necessary play in opening the handles to spread the cutting edgesapart. On the opposite side the yoke is formed with a boss 12, having ascrew-threaded aperture with which engages a headless screw 13, theinner end of which bears against the handle l.

In assembling the parts composing the shears the washer is inserted onone side of the recess 5 and a small quantity of oil placed in thecentral aperture of the washer. The other handle is then placed in orapplied to the same and the recess therein engaged with the washer. Theyoke is now slipped over the handles and one of its sides engaged withthe inclined groove 9 and the screw 13 turned so as to compress theblades between the inner end and the side seated in the groove.

A pair of shears constructed as above will be found very advantageousand elicient in use. By turning the screw the tension of the handles canbe regulated or adjusted, and as the screw is not headed it can becountersunk in the boss, preventing displacement, except by the use of asuitable screw-driver or other tool, and can also be used until entirelyworn out, as its inward movement is not limited, as is the case withscrews provided with heads. The blades are also self-sharpening.

The combined washer and oil-cup will uni- IOO formly lubricate thecontacting parts at the points necessary, and will prevent the escape ofthe oil to the cutting edges or handles, which would be liable to soilthe hands of the user and injure the material operated upon by theshears.

There are other advantages not necessary to enumerate here, but whichwill be readily appreciated by the users of the invention.

Having thus fully described my invention, what I claim isi. As animproved article, a pair of shears or other analogousinstrument,comprising the handles formed with registering circularrecesses in their inner sides, the washer seated therein, the yokeembracing said handles and one of its sides engaging with a groove inthe outer side of one of said handles and the regulating-serew passingthrough the opposite side of the yoke; substantially as described.

As an improved article a pair of shears or other similar instrument,comprising the blades having registering circular recesses in theirinner sides, a combined washer and oileup seated in said recesses,having a central oil-aperture, the yoke embracing said handles and oneof its sides engaging with a groove in one of the handles, and the screwpassing through the opposite side of the yoke; substantially asdescribed.

3. In a pair of shears or other analogous instrument, the combination ofthe handles having circular recesses in their inner sides, the washerhaving a central aperture seated in said recesses, and one of saidhandles having an inclined groove in its outer side, the rectangularyoke loosely embracing said handles with one of its sides engaging withsaid groove, the screw-threaded boss formed at the opposite side of saidyoke, and the head- 4o less screw engaging therewith; substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
